An eighteen-wheeler truck of mass 42.0x10 kg moves a speed of 32.0 m/s on a highway. Determine (a) How much work is required to slow it down to 5.00 m/s? (b) If the maximum frictional force that the road can exert on the truck is 2.00x10$N, what is the truck's displacement during that process? Ignore air resistance. Use energy approach.
